When you talk to many people about missions, you can see that what comes to mind is a safari jacket and a pith helmet. How does one explain missions to somebody who still thinks in terms of Tarzan movies? Well, I would give them Perspectives on the World Christian Movement. It is, I'll admit, a massive book. But then again, missions is a massive subject.
Winter is admirably suited to handle the task. He has been a missionary, and has been a big influence in missiology for decades, most notably in placing the stress on "unreached peoples." He is also one of the founders of the United States Center for World Mission, and one of the most brilliant men I have ever met. (He visited Vancouver to speak at a missions conference in 1981.)
Part of Perspectives is Winter's own work, but large parts of it consist of original source material, dating right back to William Carey, the father of modern missions (hence the name of the publisher.) The topics include a sweeping history of missions from New Testament times to the present, a discussion of what missions means, and a look at the unfinished task.
Perspectives is so huge and complete that it forms the basis for a college-level course, which is taught in Christian colleges, and by extension all over the world. But it certainly stands reading on its own, and should be in the library of every church, Christian school, and mission agency, and every pastor's study. It's long past time that the pith helmet image was updated.
